Hey, if the site puts it at 1906 then it could very well be. Perhaps the stock is a replacement or the refinish job just gives it a modern look. I was going by the shape of the stock mostly when thinking it was a more recent vintage.
A good gunsmith can tell you more about the rifle,....in other words whether it has been modified, had parts replaced etc.
Bottom line, ... if it's a shooter in safe working condition you've got a fine tool to be used for generations to come.
